The Impact of Motivation in Return to Work After Work Disability
The Impact of Motivation in Return to Work After Work Disability
The current research on the impact of motivation in return to work after work disability has 2 major parts: (1) a questionnaire study for which SMEC gave approval, this part is completed, (2) a RCT.
The RCT will compare two groups: (a) a consult as usual (a regular consult with the medical advisor) and (b) an intervention based on motivational interviewing performed by a medical advisor.
Work disability is a major rising problem and brings a high societal cost in European countries. The Belgian institute for public health insurance reported that costs for work disability for the first time have overgrown the costs of unemployment.
Work disability can be assessed in many ways. For a long time, a biomedical framework was used with focus on physiopathology. According to this framework, complaints and disability result from observable damage in the body (e.g., virus, fracture, lesion, etc.). Once damage is resolved, a patient is expected to resume activities and, for instance, return to work. In some cases, it is obvious that the patient is not able to work (e.g. a roofer with a broken leg) or is prohibited to resume work (e.g. a bus driver with a driving ban after an epileptic seizure). But how can the investigators explain the phenomenon that in two patients with similar pathology and complaints, the first one returns to work and the other does not? This requires a shift from a biomedical to a biopsychological perspective. The latter assumes a complex interplay between biological, psychological and even social factors on disease. A plentiful of psychological constructs have been studied in order to explain the observed heterogeneity on human suffering in the context of chronic diseases. One of these is the construct of motivation.
The research on motivation in the domain of psychology is on the rise. Binary thinking on motivation (being motivated or not) has been left behind since the introduction of intrinsic and extrinsic motivation in the 1970's by Edward Deci and Richard Ryan in their Self-Determination Theory (SDT). The SDT has been developed in the past 40 years based on scientific research and has been applied in various fields. Relatively recently this theory has been introduced to the work context and its usefulness has been proven. Research of the theory applied to the context of work disability is however still scarce.
Whereas other theories mainly look at how strongly people are motivated (a quantitative approach), the SDT emphasizes to look at the quality of this motivation. SDT suggests that higher levels of motivation do not necessarily yield more desirable outcomes if the motivation is of poor quality. The differences in the quality of motivation are associated with the regulation of the behavior being autonomous or controlled. Several studies confirm that both employees and unemployed feel better and how more desirable behaviors (e.g., search behavior, performance, helping) when having a more autonomous regulation and a less controlled regulation. For disabled, research showed that motivation can be improved through interventions helping to formulate realistic goals and empowering them to be responsible for their own participation despite their limitations. Autonomous regulation can be elicited by the individual self or by the environment by meeting the individual's basic psychological needs. SDT considers three needs as basic: the need for autonomy, need for belongingness and need for competence.
SDT is a theory that helps to understand how and why people get motivated. A framework that arose from practice and shares large similarities with SDT is Motivational Interviewing (MI). It consists of principles and techniques that are applied in order to increase client autonomy. Clients themselves generate the motivation for change, and it is a counselor's task to help clients detect ambivalence regarding behavior change, and assist them in making informed and contemplated choices to act. MI has been proven an effective approach to promote behavioral change and may therefore be especially beneficial in a RWT context as returning to work can be conceptualized as a complex human behavior change, involving physical recovery, motivation, behavior, etc. It was found that MI, in addition to routine functional restoration, is more effective than a routine functional restoration program alone in improving RTW among workers with disabling musculoskeletal disorders. Research furthermore suggested that MI may be an effective method to facilitate RTW. SDT may prove to be a useful theoretical model to understand how and why MI works within the context of RTW.
The general objective of this dissertation is to examine how motivation impacts RTW after work disability. The investigators are focusing on the question of whether motivation can be measured, and if so, whether the differences in motivation have an impact on RTW. Subsequently the question rose whether the investigators can influence motivation regarding RTW. The following research questions were investigated:
The RCT will compare two groups: (a) a consult as usual (a regular consult with the medical advisor) and (b) an intervention based on motivational interviewing performed by a medical advisor.
